Now the topic is split from the previous one it has no more relation with Windows, so it is locked.
If I'm wrong, please, PM me (or report this message to a moderator, explain why you think it should be unlocked and it might be done).

I presume, you meant to say that it is not related to Oracle, not Windows? My thoughts exactly, but I left the possibility (not probability) that further questions might involve Oracle (such as "can I install 64-bit Oracle on 32-bit Windows?").

Yes, Oracle, of course.
But as John said in his previous topic:John Watson wrote on Tue, 08 November 2016 08:54

It has come to my attention that you appear to be in a country where use of Oracle products is not legal. This board is not hosted in the US and other members may choose to assist you, but I shall not.

Difference between 32 and 64-bit Windows
There Are Many Different
1. A major contrast between 32-bit processors and 64-bit processors is the quantity of estimations every second they can perform, which influences the speed at which they can finish errands. 64-bit processors can come in double center, quad center, six center, and eight center adaptations for home registering

2. 32-bit processors and 64-bit processors is the greatest measure of memory (RAM) that is bolstered. 32-bit PCs bolster a greatest of 3-4GB of memory, though a 64-bit PC can bolster memory sums more than 4 GB.
